. To a-ZZ 'whom it may concern, Y

Be it known that I, EDWARD RrrrnNHoUsn, of 2561 N Front' St., Philadelphia, inl the county 'of Philadelphia and State Vof Pennsylvania, have inventedcertain new.` and useful Improvements in Thread Guides for Spinning Machines, whereof the following isl a specification, reference being had tothe accompanying drawings.

The invention relates to thread guides for spinning machines, and is more especially"V useful in machinesof this Y' general class adapted for spinning artificial silk.

silk, a plurality of-strands are formed by a spinneret, and after passing through a suitable coagulating solution are subsequently twisted into a single thread. Contemporaneous with this twisting action, the thread is collected in the form of an annular cake, in a receiving box rotating ata very high speed.- Thetwisting of the grouped strands, and the building of the cake in the receiving box are due-t0 the'resultant of the nate at which the strands/are fed and the centrifugal forceoccasioned by the high rotative speed already referred to. In order to obtain a perfect thread, it 'is absolutely essential that the bunched strands'of cellulose be at all times accuratelyL directed to a central point within the receiving box.,

The primary object of my invention is .to

insure the relation just described.l -To this end it includesa thread guide having acom-` paratively long counter weighted shank or stern1 freely suspended from a suitablesupa port, so as to readily yield to the vconstant i view through'thetwisting'mechanism of an j j '-"ed form in whichv the -general arrangements 5'0- and resultant functions arethe same as those angular pull of the thread occasioned by centrifugal for'ce as above lnoted and, asa

result be, automatically maintain anA accu-v rate central ceiving box.

Other objects and attendant advantages of my -invention will become readily apparent from the detailed description which f ollows. *y In the 'drawings,pFigf.' I isa cross-sectional illustrating my inventionzfv l, Y Fig. II, isAv asimilar yview-of afslightly artilicialsilk spinning Inacllir 1e l conveniently Referringto Fig. Ifofi'the drawings, kthe spindle ofthe machine designated 'by lthe numeral l, issurmount'ed byanfintegli'al col" lar 2,*which serves as aA-s'eat for .,a.jreceiving\ l shown, it consists position with respect to the re-- box 3, and displacement o f the latter is prcvented by a central stud 5, projecting from said' collar. The spindle is adaptedV to be 'driven at a high rate of speed and since thisV may be'eflected by any `approved'means, illustration thereof. has been deemed unnecessary.

The thread, guide embodying the novel features-of my invention in their simplest form, 1s represented in Fig. I.

By thls construction` the guide is freely sus- As therein pended from its support in such a manner as v to be sensitive to a delicate pull induced by gyration of the thread' as will be more clearly hereinafter described.' The lower or free end of the guide terminates in a thickened weighted portion l0, preferably spher ical in form. This serves in effect as' a stabilizer tending to hold the guide in a central position and at the. same time prevent excessive deflection of the guide from the vertical position shown. N

In the coursev of Vthe operation of the machine, the guide supporting rail 9,- is slowly reciprocated vertically so as to cause the building of the cake represented at in the box. This building action is effected through the velocity 'induced Yupon the thread by virtueof the high speed rotation of the receiving box in connection .with the v attendant.`linear movement4 of the strands pension of t'heguide, its lower endwill at all'times assume a central position withre- -spect to'the receiving boX notwithstand ing any inaccuracies ofalignment of the seat" 8, with relation tothe spindle center.

Under these conditions,.a' uniform thread is assured owing to thus esta'bli'shedLHfL I-n Fig. II, I have illustrateda slightly modi-v already described.v InffthisjA instance, the

7, and the countersunkseat 8. By this construction, the guide is primarily centered by the co-operationof the Washer 32, with the seat While the Weighted end of the guide, in finding its own center as already described, is independently permitted to shift accordingly by virtue of theinherent yielding nature. of the resilient Washer.

This second form of my invention Will` thus be operative' notwithstanding any sticking which may occur between' the Washer 32, and the seat 8, Which would ordinarily tend to defeat thedesired object of theinvenytion.

It is to be understood that I do not wish to limit myself tothe precise details of arrangement and construction herein shown since Various modifications may be made therein Without departing from the spirit cf my invention.

Having thus claim: i

1. Ina device of the character described,

the combination with a rotating spinning' box for receiving: the finished thread, of a cooperative thread guide adapted to be reciprocated axially Within the spinning box to effect distribution ofthe thread as it accumulates therein, said guide having capacity for automatic self centralization Within the receiving box under constant angular pull induced by gyrationof the thread during its spinning.

In a device of the character described, the combination with a rotating spinning box for receiving the finished thread, of a cooperative thread guide "of tubular form freely `suspended at its upperextremityso that its lower end may be automatically maintained accurately centralized Within the spinning boxl under constant angular pull induced by gyrationof the thread dura ing its spinning.

4:. In a device of the character described,

the combination With a rotating spinningv box for receiving the finished thread, of a cooperative tubular guide freelysuspended at its upper extremity and Weighted at its lower end so that the-latter may, lunder the stabilizing iniiuence of the Weighting, v yield to constant angular pull induced lby gyration of lthe thread 'during its spinning and thereby beheld automatically centered WithJ y in the spinning box.

means for loosely supporting said guide in-4 gagin'g the shank of the giiide'directly bei neath the headedportion and adapted to au! toniatically center itself in the recess of said supporting rail, the resiliency of said Washer permitting an independent play of the- Weighted free end of the guide 'with respect to said spindle substantially as shown and for the purpose set forth.' a
